To move apps to the SD, you need to do something like this:
- Insert an SD card into your device. ...
- Open Settings > Storage Settings.
- Select your SD card. ...
- Tap the menu icon (three dots) in the upper right corner.
- Tap Storage settings.
- Tap Format as internal.
- Tap FORMAT SD CARD.
- Tap Move content.
Bare in mind, not all devices support using SDs as internal storage and moving apps to them, and I don't know your device so I can't say if it does or not.. Also if you do this, the SD can't be removed, and nor can it be read by a computer or other Android device, unless reformatted. Another thing, with apps running from the SD, it can cause increased wear of the SD
